I have tried this fix but still no internet...
Sudo ping 8.8.8.8
Destination Host Unreachable

Hm, after menually selecting one the two Wifi interfaces (wlan0) to connect to the proper Wifi I got Internet again.
Let's reboot and try again. Ok in desktop mode it auto connects to the internet now to lets reboot and check in RetrOrange Pi...

Nope for some reason it is for RetrOrangePi impossible to auto connect to the WiFi without me going to the desktop first! When I go back to the Desktop enviourment I check sudo ping 8.8.8.8 and guess what? DESTINATION HOST UNREACHABLE!!!
Wifi is connected... eth0 *clicks on disconnect What do you know 8.8.8.8 is reachable...
